SLI GTX970s to Crossfire R9-290s Causing Power Surge Warning

[africanos23]

I decided to put my R9-290s (returning my daily GTX970s) as I'm waiting to order new cards. I played around for 2-3 hours and today everytime I get into a game after 2-3 minutes the system restarts and displays an error Anti-Surge message.

I'm not sure if its just to sensitive as this has not happened to me EVER. The Corsair AX1200 is roughly 3 years old but seemed ok. I've used the cards and the PSU in the past for light mining and lately only for benchmark testing for short periods of times with no trouble whatsoever other than slightly more heat than the GTX970s.


If anyone can chime in it would be appreciated.

Note: I'm not a novice builder so I have checked psu connections and all the fine details.

Here are the specs all stock btw
i7 3930K @ stock
Thermaltake air cooler can't remember the model (2x140mm)
1 SSD 1 HDD
Asus P9x79 deluxe
Ax1200

I had 3x 290 running on my Corsair AX1200.

I was running 3X290s at one point also which is strange (bought 4 of them) I gave 2 to my brother so I don't have them here atm to test maybe 1 is faulty.

Test one card at a time?

Does the PSU have split rails?

The AX1200 is single rail (if I'm not mistaken), disabling Crossfire the top card works with no antisurge problems.

What do you have the PSU plugged into ? Wall socket or (surge protected) extension ?

Straight to wall

Don't know if this has anything to do with it but in the bios the 3.3V voltage rail is showing a red 2.94v. Something that didn't occur previously.

Seen this happen a few times before. Most people tested the PSU with a digital multimeter and it read 3.3v instead of 2.9xx which indicated the bios software was reading wrong, they then turn off Asus surge reporting.

If the PSU does indeed read 2.9xx on the 3.3v rail then I would go about RMA. Think those came with a 7 year warranty.

Hope this info helps.

Thanks
